I'm the developer of the OpenGL collection extensions. I removed the extensions from my own webspace since they weren't complete and I had stopped working on them. However, it seems people like them...

Again, use luagl, it is not hard to make a hud using it.

After you are done rendering your 3d scene switch to orthogonal projection:

gl.MatrixMode( gl.PROJECTION )
gl.LoadIdentity()
gl.Ortho(...

You have to update the viewport as well, you have to use luagl for this:

gl.Viewport( x, y, width, height )

You want to set x and y to zero and set width and height to the new window size.

"Joint>Attach object..." is a dummy action, it doesn't do anything. It is one of the things I never implemented.

I put a lot of work into making these extensions and the majority of them are stable enough, the 3D sprite and Milkshape 3D extensions being the exceptions, so I'll keep them available.

As for the...

I'm dropping this project for personal reasons. I apologize for any inconvenience this might cause.

Your model stores the full path of the texture, making the RequestedTexture$ expression return not only the name of the file but the whole path. In MilkShape when you set a texture you will want to...

I have plans for a HUD extension, it wont be as flexible as having MMF objects on top of the Base window but it will be a lot faster.

An .obj model extension is definitely a possibility, but I have a couple of other things I want to finish first.

If you are only using one light source ( the spotlight ) you could call the Apply Lights action only once at start and not on redraw, this way it won't be affected by camera transformation and will...

First when you set up a new sprite ( using the Sprite>New Sprite... action ) you specify the number of directions and the number of animation frames per direction. The total number of frames will be...

I see your point, perhaps the best solution would be to have an option to automatically scale image height/width to the nearest power of two, since that wouldn't mess up texture repeating ( also no...

This is very much possible, but isn't it quite easy to manually pad using an image editing tool? ;)

It certainly would be useful. I think it would be a big project though, the format seems quite complex. It would be interesting if another extension developer would like to tackle it, I think it is...

It's the same for 3D objects. However if you use the MS3D or 3D Sprites extensions they automatically handle this for you.

Lets you create custom movements with up to 360 directions. Works in a similar fashion as the Platform Movement Object.

That's strange, it is supposed to display and animate the images in the Texture bank. Is the MS3D and 3D sprite examples that come with the collection working for you?

You can have any number of directions, so if you feel like drawing frames for 360 different directions, then there is no problem. :P

Added show/hide group actions to the MS3D extension!

Ah, you are trying to use a texture name as the material name. Use the "Material->Texture handle..." action instead, with material name "Head" and the texture handle of the desired texture.

"Set group material" works fine for me, are you sure you entered correct group and material names? They are case sensitive. If you just wish to change the texture of a material use the...

No bug, this is because the image data of an active object is shared among all its instances. Probably to save space.

Of course XLua and .net support will stay. No need to worry. ;)

The code looks ok, did you replace the base object ( removed it and inserted a new )? The latest build of the base object is not compatible with previous builds, so you may need to do that.

Your intuition is pretty much spot on. ;)
